Arm_def is not used as-is by Bezier algorithms.  It describes Bezier curves in a
format that I find easier to control.  The format is described in the user
manual.

The macro SSwp_Bezier() converts Arm_def to Arm_pts.  Arm_pts is the
one-dimensional array of control points that is in the form expected by Bezier
algorithms.  If you look at the message window from a spheresweep_cockpit.pov
render, you will see the Arm_pts array in its final form.

Arm_rs is the array of the radii that correspond to the control points.
